[0002] Vending machines are commonly used equipment in commercial automation. They are not restricted by time and place, can save manpower and facilitate transactions. They are a new form of commercial retail, also known as 24-hour mini supermarkets.

[0003] Vending machines usually have a refrigeration or freezing function, that is, the vending machine cabinet is cooled by a refrigeration module. The refrigeration module is usually composed of a compressor, an evaporator, and a condenser. Among them, the function of the condenser is to cool the high-temperature and high-pressure refrigerant gas into a low-temperature and low-pressure liquid so that it can re-enter the evaporator for heat absorption and refrigeration. The existing evaporator will discharge a certain amount of condensed water during the heat exchange process. The usual way to deal with it is to discharge the evaporator's drain pipe directly to the outside. Outdoors, especially in environments with relatively harsh temperatures, some insects will crawl into the drain pipe due to the high outdoor temperature, causing the drain pipe to be blocked, reducing the working efficiency of the refrigeration module, and even causing damage to the refrigeration module.

[0004] In view of this, it is necessary to propose a new technical solution to solve the above technical problems. Summary of the Invention

[0037] Embodiment 1

[0038] See Figures 1-5 As shown, a refrigeration module includes a condenser 1, a compressor 2, an evaporator 3 and a mounting rack 4 installed on a vending machine. The condenser 1, the compressor 2 and the evaporator 3 are respectively installed on the mounting rack 4. It further includes a water sealing mechanism 5 which is installed on the mounting rack 4, and a drain pipe 31 of the evaporator 3 is connected to the water sealing mechanism 5. Through the arrangement of the water sealing mechanism 5, the drain pipe 31 is kept in water for a long time, preventing insects from entering the evaporator 3 through the drain pipe 31 and causing blockage. The structure is simple and the practicability is strong.

[0039] In a further specific embodiment, the water sealing mechanism 5 includes a water storage box 51 which is installed on the mounting rack 4. The water storage box 51 is provided with a water guide pipe 511, and the drain pipe 31 is connected to the outer end of the water guide pipe 511. During use, the evaporator 3 discharges condensed water into the water storage box 51 through the drain pipe 31. As the condensed water is discharged for a long time, the water level line in the water storage box 51 gradually rises until it covers the drain pipe 31. At this time, the water sealing mechanism 5 completes the sealing of the drain pipe 31, thus preventing insects from entering the drain pipe 31.

[0040] In a further specific embodiment, a water storage cavity 512 is provided in the water storage box 51, and the inner end of the water guide pipe 511 communicates with the water storage cavity 512. Through the arrangement of the water storage cavity 512, the condensed water is collected, and the condensed water overflows the water guide pipe 511, thereby sealing the drain pipe 31 with water and preventing insects from entering the drain pipe 31.

[0041] In a further specific embodiment, a water outlet groove 513 is formed in the water storage box 51, and the water outlet groove 513 communicates with the water storage cavity 512. Through the arrangement of the water outlet groove 513, when the water level line in the water storage cavity 512 reaches the water outlet groove 513, water overflows from the water storage box 51 and is evaporated by the heat dissipation copper pipe 21 of the compressor 2.

[0042] In a further specific embodiment, a cover plate 514 is rotatably installed on the water storage box 51, and the cover plate 514 covers the water outlet groove 513. When the water level line in the water storage cavity 512 exceeds the lowest point of the water outlet groove 513, under the condition of internal and external pressure difference, water will push open the cover plate 514 and enter the evaporation box 52. Through the arrangement of the cover plate 514, the drain pipe 31 can be better isolated to prevent other smaller insects from entering the drain pipe 31 through the water storage box 51.

[0043] In a further specific embodiment, two clamping grooves 515 are recessed downward on both sides of the water outlet groove 513 of the water storage box 51, and clamping pins 516 are arranged on both sides of the cover plate 514. The two clamping pins 516 are respectively clamped with the two clamping grooves 515. It should be noted that the cover plate 514 of this embodiment is rotatably installed on the water storage box 51 through the clamping pins 516 and the clamping grooves 515. This setting has a simple structure and is convenient for installation.

[0044] In other specific embodiments, a compression spring can be arranged on the clamping pin 516, so that the cover plate 514 is always in a state of closing the clamping groove 515.

[0045] In a further specific embodiment, the bottom of the water outlet groove 513 is higher than the top of the water guide pipe 511. Through this setting, when the water level line exceeds the bottom of the water outlet groove 513, the water in the water storage box 51 will submerge the water guide pipe 511, which can further prevent insects from entering the drain pipe 31 through the water guide pipe 511.

[0046] In a further specific embodiment, the water sealing mechanism 5 further includes an evaporation box 52. The evaporation box 52 is installed on the mounting frame 4, the water storage box 51 is installed on the evaporation box 52, the compressor 2 is provided with a heat dissipation copper pipe 21, one end of the heat dissipation copper pipe 21 is connected to the compressor 2, and the other end of the heat dissipation copper pipe 21 penetrates through the evaporation box 52. The compressor 2 is installed on the evaporation box 52, and the middle part of the heat dissipation copper pipe 21 is laid flat on the evaporation box 52.

[0047] The heat dissipation copper tube 21 mainly serves as a channel for the refrigerant, ensuring the correct flow of the refrigerant in the system and achieving heat transfer and dissipation. Therefore, by having a certain amount of heat, the copper tube is laid flat on the evaporation box 52, which can heat the water in the evaporation box 52 to a certain extent and accelerate its evaporation rate.

[0048] It can be understood that a heightening block is provided in the evaporation box 52, and the compressor 2 is installed on the heightening block. By means of the heightening block, the height of the compressor 2 is increased to prevent excessive condensate in the evaporation box 52 from coming into contact with the bottom of the compressor 2.
